SPECIFICATION forming part of Letters Patent No. 601,544, dated March29, 1898.

Application filed July 2, 1897. $erial No. 643,276. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM H. BENNETT, of Athlone, in the county ofRockingham and State of Virginia, have invented certain new and usefulImprovements in Plows and Cultivators; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

This invention relates to improvements in plows and cultivators, theobject of the same being to provide improved attaching means whereby theshovel may be readily attached to the standard and removed therefromwhen desired, the same being held rigidly in position by the fasteningdevice.

The invention consists in certain novel features of constructionhereinafter fully described and claimed.

In the accompanying drawings, Figure 1 is a side view of a portion of ashovel-standard, showing my improvement applied thereto, the shovelbeing illustrated in position upon the standard. Fig. 2 is a sideelevation of the lower end of the shovel-standard with the shovelremoved. Fig. 3 is an end view of the lower end of the standard with theshovel removed. Fig. etis a view of the shovel.

Referring to the accompanying drawings, 1 indicates the shovel-standard,which is provided on its opposite sides, at its lower end, with thelongitudinally-extending slots 2, which form the central tongueor webportion 3. The lower end of the standard is slotted transversely, asillustrated at 4, said transverse slot communicating with the lower endsof the longitudinal slots, as illustrated. Raised from the rear side ofthe standard are the lugs 5, between which is pivoted the lever 6,carrying at its lower end the lockingpin 7, which extends through aperforation 8 in the rear wall of the transverse slot. A coiled spring 9is positioned in a cavity 10, formed in the rear side of the standard,beneath the upper end of the operating-lever, against which it bears,thus serving to hold the locking-pin normally projected through the wallof the standard.

11 is a shovel provided adjacent its upper end with a central slot 12and a perforation 13 at the lower end of said slot. This shovel isadapted to be inserted within the slotted end of the standard, the webportion of said standard taking into the slot formed in the shovel. Theshovel is inserted in the standard until its perforation is in line withthe perforation of the standard, the locking-pin being raised in themeantime by pressure upon the operating-lever, so that when saidperforations are in line the locking pin passes therethrough, when theoperating-lever is released and secures the two parts rigidly together.

The locking pin and mechanism being on the rear side of the standarddoes not in any Way interfere with the plowing.

I do not limit my invention as a securing means for attaching the shovelto the standard, as it may be used in many other connections-as, forinstance, in securing the teeth of cultivators in position.

From the above description it will be seen that I have produced animproved locking device for detachably securing the shovel to thestandard whereby the shovel may be quickly and readily removed from thestandard or positioned thereon as desired.

Having thus described the invention, what a is claimed as new is 1. Thecombination with a slotted shovelstandard having slotted sides and endand a central web portion of a shovel provided with a slot adapted toreceive the central web portion of the standard, a locking-pin adaptedto project through the standard and shovel, and a spring-catch operatinglever for hold-. ing said pin normally engaging the standard and shovel,substantially as described.

2. The combination with a shovel-standard having longitudinal slotsformed in its lower ends on opposite sides thereof and forming a centralweb portion, said standard formed with a transversely-extending slot atits lower end which communicates with the lower ends of the longitudinalslots, an operating-lever pivoted to the standard, a locking-pin carriedby the lower end of the operating-lever and adapted to project through aperforation in the standard, of a shovel provided at its upper edge witha central longitudinal slot to receive the central web portion of thestandard and with a perforation to receive the locking-pin, and a springpositioned in specification in the presence of two subscribthe cavityformed in thelshovel-siclailllaigd and in g Witnesses. engaging theoperatingever to 0 t e pin normally projected through the perforationsWILLIAM BENNETT 5 of the standard and shovel, substantially asWitnesses:

described. i J. W. HINTON, In testimony whereof I have signed this GEO.W. HESS.
